Airtac PB Pen-type Cylinder PB16X75SR
The AirTAC Airtac PB Pen-type Cylinder PB16X75SR is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 75mm stroke. Its slim round barrel and back cover are stainless steel, the M5×0.8 ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB16X75SR
The AirTAC PB16X75SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 16mm bore and a 75mm stroke, generating 100.5 N of push and 90.7 N of pull at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, while keeping end-of-arm tooling lightweight.
This variant includes an R axial air inlet for in-line plumbing and a built-in piston magnet (-S) for position sensing. Air is supplied via an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling. It relies on a fixed TPU bumper at each end to decelerate the stroke, meaning you should meter-out the exhaust or add an external shock absorber when moving heavy tooling at high speeds.

Specifications follow the official AirTAC PB pen-size datasheet. Piston rod and barrel are stainless steel. Confirm bore, stroke and back-cover option against the product label before installation.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 N |
Values are taken from the AirTAC PB thrust table. Because pull acts on the rod-side annular area, pull force is always lower than push. Actual usable force is reduced by friction — size with a margin.

Where the Airtac PB Pen-type Cylinder PB16X75SR Is Used
PCB Depanelling Ejector
Uses the 100.5 N extend force to push severed circuit boards out of a routing fixture, where the slim stainless body avoids clashing with the spindle head.
Carton Flap Tucking
Cycles rapidly at 50-800 mm/s to tuck minor flaps on a packaging line, with the fixed TPU bumper absorbing the repeated impact of the 75mm stroke.
Light Vertical Lift Gate
Raises a 5.1 kg pneumatic分流 gate (matching the 2:1 safety margin of the 0.5 MPa force) on a conveyor, requiring an external guide to protect the thin 5mm rod.
Is the Airtac PB Pen-type Cylinder PB16X75SR the Right Cylinder?
Choosing this 16mm bore provides the highest standard force in the PB family, offering a safe working load of roughly 60 N (about 60% of the 100.5 N @0.5 MPa figure) for smooth travel. If you need less force to save space, the 12mm bore outputs 56.5 N push at 0.5 MPa; as 16mm is the largest available, stepping up requires a different cylinder family. A plain PB cylinder will drift and cannot hold a load if air pressure is lost, so an external rod lock is required for fail-safe positioning. Confirm your ordering essentials: 16mm bore, 75mm stroke, M5x0.8 port, S magnet, R axial inlet, and no mount bracket.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Slim pen body vs. a standard round cylinder
- ✓ Back cover: CB / U / R inlet direction
- ✓ Magnet (S) for sensors?
- ✓ Mounting: LB / FA / CJ or front thread
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
- check Installation by qualified personnel per AirTAC docs.
Airtac PB Pen-type Cylinder PB16X75SR FAQ
At 0.5 MPa, the push force is 100.5 N and the pull force is 90.7 N. At the maximum operating pressure of 0.7 MPa, the push is 140.7 N and the pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
No, a plain PB cylinder drifts if air is lost and the fixed TPU bumper only decelerates near stroke end; it does not lock the rod. For vertical holding, you need an external rod lock. The built-in -S magnet allows position detection using either AirTAC reed (mechanical) or electronic (solid-state) switches.
